ANDREW ALFORS, OF HANNA, WYOMING.

LOCK.

SPECIFICATION forming part of Letters Patent No. 554,566, dated February 11, 1896. Application filed August 10, 1895. Serial No. 558,879. (No model.)

To all whom, it may concern:

Be it known that I, ANDREW ALFORS, of Hanna, in the county of Carbon. and State of lVyoming, have invented a new and useful Improvement in Locks, of which the following is a full, clear, and exact description.

My invention relates to an improvement in looks especially adapted for trunks, boxes and like articles, but which may be otherwise employed if desired.

The object of the invention is to provide a lock which will be key-operated and constructed in a simple and economic manner, the construction of the lock being such that the key when introduced cannot be Wi thdrawn from the lock unless the tumblers of the latter are carried to locking position.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth,

and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a box and of the lock applied to the box, the lock being closed. Fig. 2 is an inner face View of the two sections of the lock opened out. Fig. 3 is a section taken horizontally through the body of the lock, the sections being closed one upon the other. Fig. 4 is a vertical section through the entire lock and the key, the lock being shown in looking position; and Fig. 5 is a front elevation of a latch-plate or keeper used in connection with the look.

In carrying out the invention the lock may be said to consist of a face-plate A and a body portion 13, the face-plate having a hinged connection with the body. The body is preferably given a circular shape, but may be otherwise fashioned, and the face-plate, against which the body is adapted to bear, is sometimes and preferably made with a flange 11 at its upper edge, adapted to rest upon a horizontal surfaceas, for example, the upper edge of the body of the box 0. The faceplate is provided with the usual openings 12 for the introduction of screws or other fastening devices, and the body is provided with a stud 13, preferably located near the margin and adapted to extend over the flange 11 of the faceplate when the body and said plate are brought in engagement.

The bolt and its operative mechanism are contained in the body B of the lock, and upon the inner face of the body an opening 14 is made, adapted to receive a keeper 15 formed upon the face-plate, and said keeper is usually of angular construction or is provided with a slot 16 in its under face, as shown in Fig. 4.

The bolt 17 is preferably of segmental shape, approximating a disk, and is adapted to turn upon a centrally-located pivot 18, as shown in Fig; 3. In a portion of the peripheral surface of the bolt a cavity 19 is made, of practically the same width as the opening 14 in the body, adapted to receive the keeper 15, and at the opposite side of the bolt its peripheral surface is recessed to form two shoulders 20 and 21, which by engagement with a pin 22, located between the shoulders and upon the back of the body, limits the throw of the said bolt in either direction.

The body of the lock is held securely against the face-plate A by causing the keeper of the latter to enter the opening 14 in the body, the recess 19 in the bolt registering with said opening 14 in the body. The bolt is then turned in order that the space between one of the shoulders and the aforesaid recess 19 shall align the slot 16 in the keeper 15, as illustrated in Fig. 4.

The pivot-pin 18 for the bolt is virtually a post, as shown in Fig. 4, and is adapted to enter the bore in the barrel of the key 23, a suitable keyhole 24 being made in the outer face of the body, and this key is provided with a bit 23, adapted to enter an opening 25 made in the bolt, as shown in Fig. 3. The movement of the bolt is retarded, so that it cannot be moved out of position except by means of a key, and to that end the portion of the periphery of the bolt locatedbetween the recess 19 and shoulder 21 is provided with a ratchet-face 26, or is otherwise roughened to receive a spring-detent 27, secured within the case.

A latch-plate 28, which is also a keeper, is to be secured to the lid of the box 0, for example, and this latch-plate has an opening 29 therein to receive the stud 13 of the body of the look when the latter is locked to the face-plate. Under this construction it will be observed that when the bolt is in looking engagement with the face-plate and the lid of the box is closed the lid cannot be opened until the bolt is thrown.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a lock, a face-plate provided with a keeper, a body-section having hinged connection with the face-plate, a rotating keyactuated bolt carried by the body-section and adapted for engagement with the said keeper, and a retarding device offering resistance to the movement of the bolt, substantially as described.

2. In a look, a faceplate having a keeper located thereon the said keeper being pro vided with a head, a body-section provided with an opening to receive the said keeper, a rotating key-actuated bolt pivoted to rotate past the said keeper-opening in the body and having a recess adapted to register with the said keeper opening, the said bolt being adapted when turned to engage the head of the keeper, and a retarding device offering resistance to the movement of the bolt, substantially as described.

In a look, a face-plate having a keeper proj ectin therefrom, a body-section provided with an opening to receive the said keeper, a segmental key-operated bolt. mounted to revolve and adapted to engage said keeper, means for limiting the rotary movement of said bolt, the said bolt being provided with a recessadapi'ed to register withthe keeperopening in the body-section, and a ratchetand-pawl mechanism serving as a retarding device for the bolt, as and for the purpose specified.

4. In a lock, a face-plate, a body-section having hinged connection with the face-plate, a keeper located on the face-plate and adapted to enter an opening in the body, a bolt pivoted to rotate past the said keeper-opening in the body, which bolt is provided with a recess adapted for registry with the keeperopening in the lock-body, the said bolt being further provided with a retarding mechanism, a post carried by the body of the lock, and a latch-plate having an opening adapted to receive the said post, as and for the purpose set forth.

5. In a look, a face-plate, a body-section having hinged connection with the face-plate, a keeper located on the face-plate and adapted to enter an opening in the body, a bolt pivoted to rotate past the said keeper-opening in the body, and provided with a recess adapted to register with the keepei opening in the body-section, shoulders in one edge of said bolt adapted for engagement with a stop, teeth formed upon a portion of the periphery of said bolt, and a spring-detent engaging with the said teeth, as and for the purpose set forth.
